Amazon uses different image sizes and compression levels for the same book when delivered in different formats or to different device classes.

The cover image file you get using From KFX is whatever is contained within the KFX file you converted.

Not using this plugin.

You can change the cover image using calibre if you find one that you like better.

If you want that done it is up to you to accomplish it using something other than this plugin.
